Outline of Final Research Achievements

The esters of monolignols with phenolic acids have been found in cell walls of plants including grasses and palms. To utilize effectively to these cell walls, the modification of the cell walls are required. However, the fundamental knowledge for the biosynthetic mechanism has not been well-known. In this study, we aims at identifying acyltransferases from several plants for monolignols to lead engineering linognocelluloses in these crops. We found a novel p-coumaroyltansferase for monolignol from asparagus, and identified two candidate genes for acyltransferases highly expressed in poplar developing xylem.
